Enum Reference 

pub enum Reference {
    Call,
    Data,
    Address {
        bytes: u8,
    },
}

What kind of thing a relocation is asking the linker for.

The first two are the distance from the end of an instruction to something, which is what every reference the code makes is, because this compiler generates position independent code and nothing else. They are told apart because the linker may answer one of them with a stub and may not answer the other one that way. The third is not a distance at all and is the only kind an image asks for, since an initializer holding the address of something holds the address itself.

Variants

Call

A call, which the linker may satisfy with a stub that reaches further than the four bytes would. R_X86_64_PLT32 on ELF, and the same relocation a branch gets on the other two.

Data

A datum, reached from the instruction pointer. R_X86_64_PC32 on ELF.

Address

The address itself, written into an image. int *p = &y; and nothing else in C.

Fields

bytes: u8

How many bytes of it are written, which is the pointer width except on a target with a narrower relocation for it. R_X86_64_64 and R_X86_64_32 on ELF.
